l Glaim'. (01. 48 -1180) This invention relates to the official class offuel mixers and more particularly a new and novel liquid fuel mixer forinternal combustion engines.

The primary object of this invention resides in the provision of aliquid fuel mixer for internal combustion engines to crack andhomogenize vaporized fuel flowing from their carburetors to their intakemanifolds so as to increase the efficiency of the engines and reduceconsumption of the fuel.

Another object of this invention resides in the provision of a liquidfuel mixer for internal combustion engines adapted to be operated by arotating element of the engine.

A further object of this invention resides in the provision of a liquidfuel mixer for internal combustion engines adapted to be disposedbetween their carburetors and intake manifolds without altering thesame.

A still further object of this invention resides in the provision of aliquid fuel mixer for internal combustion engines adapted to crack andhomogenize vaporized fuel flowing from their carburetors to their intakemanifolds and force it into the combustion chamber of the engines underpredetermined pressures.

Aside from the foregoing objects, this invention resides in theparticular construction of the liquid fuel mixer.

With these and other objects in view, this invention resides in certainnovel features of construction and arrangement of elements to behereinafter more particularly set forth in the specification,illustrated in the accompanying drawings and pointed out in the appendedclaim and, although this disclosure depicts my present conception of theinvention, the right is reserved to resort to such departures therefromas come within the scope of the claim.

In the accompanying drawings forming a part of this application;

Fig. 1 is a plan view of a portion of an internal combustion engineshowing the liquid fuel mixer disposed thereon.

Fig. 2 is a side view thereof.

Fig. 3 is a plan view of the mixer per se.

Fig. 4 is an enlarged vertical sectional view taken approximately online 4-4 of Fig. 3.

Fig. 5 is an enlarged horizontal sectional view taken approximately online 5-5 of Fig. 2.

In the present illustration of this invention the letter A indicates theforward portion of an internal combustion engine which, among other wellknown elements, includes an intake manifold B,.carburetor C andgenerator D driven by a belt E in the usual manner. 1

Secured between the outlet end of the carburetor and inlet end of theengine is a liquid fuel mixer 5, forming the subject matter of thisinvention, which consists of upper and lower sections 6 and 1 providedwith substantially semielliptical bores 8 and 9 reduced in area at theirouter ends to form circular ports I0 and I I adapted to register withthe outlet and inlet ports I2 and ll! of the carburetor and intakemanifold when secured therebetween. Said semi-circular bores, whendisposed in opposed relation, form fuel cracking and mixing chambersfans It secured to a shaft l4 rotatably seated in suitable bearings I5formed between the opposed inner surfaces of the aforesaid sections withone end thereof extending outwardly through the front wall W of themixer and provided with a gear I6 meshing with a gear I! on a suitablepower transmitting cable I8 operated by a pulley 19 or the like engagingthe belt of the aforesaid generator. Said cable with the gear H5 andpulley l9 thereon is secured at one end to the generator and at itsother end to the intake manifold or other convenient place on the engineby suitable brackets 20'. The aforesaid bearings are preferably of theself lubricating type sealed between opposed sockets S formed in theinner surfaces of said sections.

The aforesaid fans l3 are preferably of the squirrel cage type hereinshown as consisting of a plurality of suitably shaped spokes 2|extending radially from laterally spaced hubs 22 and connected by aplurality of circumferentially arranged arcuate blades 23 secured to anddirected inwardly of rims 24 secured to the outer ends of said spokes.However, it is within the purview of this invention to substitute anywell known type of fan for those set forth just so the salient featuresof this invention can be practiced.

In order to seal the sections of the mixer against leakage, a suitablegasket K is disposed between their opposed inner surfaces whereupon thesections so assembled form a unit to be tightly secured between theoutlet end of the carburetor and inlet end of the intake manifold bysuitable gaskets L and bolts J of the usual type used for such purpose.

Slidably disposed in the mixer in close proximity to the fans thereinare pressure plates P adapted to control flow of the cracked andhomogenized fuel to the intake manifold.

Although the fuel mixer is herein shown as provided to operate withcarburetors and intake manifolds having companion fuel ports therein, itis to be understood that it may be constructed to fit any type ofcarburetor and intake manifold or, in fact, any fuel intake system ofinternal combustion engines.

With this invention fully set forth, it is manifest that a liquid fuelmixer is provided for internal combustion engines which will treatvaporized fuel flowing from their carburetors to their intake manifoldsso as to break up all large particles of unvaporized fuel and homogenizethem to form a unified combustible vapor to be used in operating alltypes of such engines wherever used.

Having thus described my invention, what I claim and desire to protectby Letters Patent is:

A liquid fuel mixer for internal combustion engines comprising companionsections with opposed inner surfaces and having fuel mixing chamberstherein communicating with outlet ports, a gasket disposed between theopposed inner surfaces of said sections, squirrel cage type fansdisposed in said chambers, a shaft journaIled in opposed recessesbetween the opposed inner surfaces of said sections with one end thereofprojecting through the mixer and its opposite end terminating inwardlyof the adjacent Walls of the sections, adjustable pressure platesextending laterally into the mixing chambers below the fans, a gearsecured to the outer end of said shaft. and means securing said sectionstogether into a unit.
